Difference Between Axial Flow Fan And Centrifugal FanIssuing time:2021-12-07 14:07 Difference Between Axial Flow Fan And Centrifugal Fan Fans are mainly used in metallurgy, petrochemical, electric power, urban rail transit, textiles, ships and other areas of the national economy and various places for ventilation.
With the continuous intensification of competition in the wind turbine manufacturing industry, mergers and acquisitions and capital operations among large wind turbine manufacturing enterprises are becoming increasingly frequent. Domestic outstanding wind turbine manufacturing enterprises are increasingly paying attention to the research on the industry market, especially the in-depth research on the industrial development environment and product buyers. Mob/WeChat:13676219124 MKT@popula-air.com www.popula-air.com Due to the rapid development of the fan industry in China, and the wide variety of products, in order to better meet the market demand, domestic outstanding fan manufacturers continue to strengthen the adjustment of product structure, from traditional products to new energy-saving fans and other directions, in order to achieve sustainable development of enterprises. At present, the fan industry in China is in a period of rapid growth, with huge market potential.
General ventilation fans (mostly small and medium-sized centrifugal fans and axial fans) are most widely used. What are the differences between centrifugal fans and axial fans? This is the focus of our talk today. Mob/WeChat:13676219124 MKT@popula-air.com www.popula-air.com Centrifugal fan: its impeller rotates in the opposite direction to that of the inlet and outlet air ducts, but in the same direction as the inlet. Therefore, the centrifugal fan relies on the impeller to continuously deliver gas to achieve the purpose of increasing air flow and pressure.
Axial flow fan: it also has the function of increasing air flow and pressure by continuously conveying gas through the impeller, but this fan usually adopts axial flow and the impeller is at a certain angle. Mob/WeChat:13676219124 MKT@popula-air.com www.popula-air.com
Difference Between Axial Flow Fan and Centrifugal Fan:
1. Exhaust direction: the exhaust direction of the Axial Flow Fan is straight along the axis, the air inlet and outlet of the fan are on the same axis parallel line, and the exhaust direction of the Centrifugal Fan is perpendicular to the air inlet direction, which can achieve 360 degree specified direction exhaust.
2. Structure: the impeller of the Axial Flow Fan adopts a single wing structure. The single blade rotates to drive the wind wheel, making the air form a spiral movement; The impeller of the Centrifugal Fan is a double wing structure, and the double blades rotate to drive the wind wheel.

Installation method: the Axial Flow fan has only one inlet and one outlet (it can be directly installed on the wall or in the outdoor hood or connected to the air duct). The Centrifugal Fan is generally directly installed on the air duct, and if there are special requirements, the suspender shall be connected.
4.Scope of application: Axial Flow Fans are generally suitable for conveying non corrosive gases, and allowed to contain high solid particles, corrosive gases and liquids, and the temperature is not higher than 120 ℃, and the pressure is not lower than 1.6 MPa. Mob/WeChat:13676219124 MKT@popula-air.com www.popula-air.com 5. Noise level: Axial Flow Fan generally works at - 20~70 dB (A), which can be selected according to needs, and centrifugal fan works at 100~150 dB (A). m 6. Price: the price of Axial Flow Fan is relatively cheap, generally 1000~3000 yuan/set. Mob/WeChat:13676219124 MKT@popula-air.com www.popula-air.com 7. Maintenance: Axial Flow Fan is a mechanical device without power, with stable performance and high reliability, which can operate continuously for several years; The Centrifugal Fan needs regular inspection and maintenance during its operation to ensure normal operation.
8. Appearance: the Axial Flow Fan is basically cylindrical in appearance, and the Centrifugal Fan is snail in appearance. Mob/WeChat:13676219124 MKT@popula-air.com www.popula-air.com
Conclusion: Axial Flow Fan and Centrifugal Fan are very different in practical application, so we must pay attention to the difference between them in actual use, so that we can correctly choose the Axial Flow Fan and Centrifugal Fan suitable for our own use, which has a great effect on improving work efficiency, reducing noise, energy saving and consumption reduction.
